NAPHTHA-GAS LANTERN.

SPECIFICATION forming part of Letters Patent N0. 245,763, dated August 16, 1881.

Application liled July 19, 1880.

To all whom it may concern:

Be it known that I, WILLIAM NV. AUSTIN, ot' Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Naphtha-Gas Lanterns, of which the following is a specification.

The object ot Iny invention is to provide a lantern with means of generatin g 11 aphth a-gas, to be burned within the same; and it consists in the construction, combination, and arrangement of a naphtha-chamber above the glassbody portion ot' the lantern, and the connection of one or more pipes or tubes, extending downward therefrom and terminating within the transparent portion of such lantern in a suitable burner, with other details of construction, as hereinafter more fully described and set forth.

The ligure represents a section view of a naphtha-gas lantern constructed according to my invention.

A represents the glass-bod y portion of a lantern of usual construction, and B represents a reservoir for containing the naphtha or other hydrocarbon liquid, and to the top ot' which is secured a handle or bail, C, connecting directly with the screw cap or plug D, connecting with the interior of the reservoir B, to admit the introduction ofthe hydrocarbon liquid, which passes through the vertical tubeE and falls upon the horizontal shield or disk F into the upper gasoline-chamber, G, until it is filled to the top end of the short vertical tube H, thence through it into the lower gasoline'chamber, J, which is filled in like manner, whereby two carbureting-chambers are formed. The air entering into the upper chamber, G, through the perforations t contacts with the vapor arising from the naphtha contained therein, thus forming illuminating-gas, which passes downward through the short vertical tube H, whence it receives a like vapor from the naphtha contained in the lower charnber, J, andthen passes downward through the tube K to the burner, as hereinafter described; or, instead of the horizontal plates, a series of horizontal partitions maybe provided with short lling-tubes, the open ends of which extend downward below the horizontal partitions slightly more than their opposite upper (No model.)

ends do above the said partitions, which may be increased to any number desired, so as to allow air to pass into the said chambers G and J through the perforations t formed through the cap or plug D, which may be turned so as to close the said openings more or less, as may be desired, to regulate the naphtha-gas formed, which passes downward through the tube K within the glass or transparent bodyA, where it is formed with a curve, so as to present a vertical outlet or burner, I, at or near the center of such cyliudric glass portion A, as shown; or the tube K may be formed to pass outside ot' the glass body in one or more branches, if

desired, and then bent inwardly or centrally, so as to enter the bottom portion, L, of the lantern, and thence upward within the glass body or chimney, as above described. This base or b ottom portion, L, may be provided with a series of perforations or air-inlet holes, S, which are closed more or less by movement of the perforated concentric ring or band T or any other suitable device to regulate or adjust the size of the openings may be employed to accomplish the purpose.

Having thus described my invention, what I claim is l. An air-carbureting lantern consisting of one or more liquid-reservoirs and one or more carbureting-chambers, forming the top portion of the lantern, and arranged concentricall y with the transparent body or globe portion and burner thereof, said burner being connected with the carbureting-chamber by a gas-tube passing down inside ofsaid globe, substantially as described, as and for the purposes set forth.

2. The combination, with the transparent globe or body portion of the lantern surrounding the burner, of one or more carburetingchambers, and one or more liquid-reservoirs arranged concentrically with each other, and having air-inlet passages at the top, and provided with a gas-conducting pipe and adjustable air-inlet passages in the base thereof, substantially as described, as and for the purposes set forth.

WILLIAM w. AUSTIN.
